Hi Rob,
we got it working. It was the clock generation chip, which provided the main clocks for the ADC and the FPGA.
We use a LMK04821. We read out the regitsters for the lock bits, they were sets, but the clock signal had a huge jitter.
We found two…
Part Number: ADC31JB68 Other Parts Discussed in Thread: LMH5401 , LMH6553 , TINA-TI Hi, I will use the ADC31JB68 device in my design and I am looking for a drive to it for unbalancing to balancing convertion.
The input signal goes from DC to 200MHz.
Do…
Part Number: ADC31JB68 Hi, since the ADC31JB68B has a small input range (1.7Vpp) I did not find any kind of TVS or zener that I could use to protect it against over voltage.
I would like to know if you have any suggestion?
Thank you,
Rodrigo
Part Number: ADC31JB68 Hi, the ADC31JB68 datasheet shows the baluns in the "current configuration mode" to convert the unbalanced to balanced signal in the analog input.
Is there any special requirement to use this structure of the baluns for…
Part Number: ADC31JB68 Hello, I will have only one ADC31JB68 connected in a FPGA (JESD204) in my design. As there is no multiple devices does I need to use the SysRef signal input of the ADC? If no, can I tie the SysRef input to zero?
Thank you,
Rod…
Part Number: ADC31JB68 Hi Team,
We have received this inquiry from our customer,
I have an analog signal with wider dynamic range than the ADC can handle, so the signal could regularly exceed the ADC's analog input range. These excursions will typically…
Part Number: ADC31JB68 Hi,
I am trying to make sense of the input rating given in the absolute maximum ratings and Full-Scale range.
In the absolute maximum ratings (page 6 of the datasheet), VIN+and VIN- can be up to 0.75V above or below VCM without any…
Part Number: ADC31JB68 Hello,
Is there an evaluation board for ADC31JB68, that I can interface with an Intel FPGA Dev Kit?
Is there any JESD204B serial interfaces firmware that's available, and that targets an Intel FPGA?
Thanks,
Mircea
Part Number: ADC31JB68 Hi Sir,
Could you please help double check the impedance of PCB traces for the ADC31JB68RTAT?
What's the PCB traces impedance for the pin4 and pin5 of ADC31JB68RTAT? Is 50ohm or 100ohm should I use?
Could you please provide…
